”A professor at Keele University in Staffordshire, England, claims to have invented a memory chip that can hold enough information to fit the entire contents of the British Library onto a single chip.
Ted Williams, emeritus professor of electronic engineering, has patented a solid state memory system with a capacity of 86GB per square centimeter of surface area, says Mike Downey, managing director of Cavendish Management Resources, the company that has been contracted to handle all commercial aspects of the technology.
“It uses a magneto-optical system which is similar to the CD-ROM and can be used as computer and processor memory for credit cards and smart cards, among other things. There is enough capacity to fit 3.4TB of memory within the surface area of a credit card,” Downey says.
The cost of producing the chip is estimated to be less than $43.60 per unit with the physical size (if the chip uses the computer’s processor) measuring 3 centimeters by 3 centimeters, with a height of 1.5 centimeters.”
